COMB.

SPECIFICATION forming part of Letters Patent No. 399,032, dated March 5, 1889.

Application filed July 2G, 1887. Serial No. 244,797. (No model.)

To all whom t 11mg/ concern:

Beit known that l, HENRY G. GUILD, a citizen of the United States, and a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Combs and their Manufacture, of which the following is a specification.

My invention relates to toilet-combs with independent teeth, or teeth not integral with the comb-head, and to the manufacture of combs of this character.

The object of my invention is, in the main, to provide an improved method of securing the metal teeth in the sheet-metal head; but its object is also to provide guard-teeth formed integrally with the head, all as will be hereinafter set forth.

'My invention will be fully described hereinafter, and its novel features carefully defined in the claims.

In the drawings which serve to illustrate my invention, Figures l, 1, and lb illustrate the blank of sheet metal destined to form the comb-head and integralguard-teeth. Fig. l is a plan, and Fig. l an end, view of the plate cut to form the head, and Fig. lb is an end view of said plate after it has been folded. Fig. 2 -is a view of the finished comb; and Fig. 3 is a transverse section of same, taken in the plane of one of the teeth. Figs. 4 and et are views on a large scale, designed to illustrate the manner in which the metal head is pressed in between and around the teeth. Fig. 5 is an elevation, and Fig. G is a transverse section, illustrating a slight variation in the con struction of the comb, that will be hereinafter explained; and Fig. 7 is a det-ached view, ou a larger scale, illustrating the perforated troughlike strip used in the construction illustrated in Figs. 5 and 6. Figs. 8, 8a, and 8b illustrate a modification of my invention where the head ot the comb is formed of two pieces or parts,

and Figs. 9 and 9a show a cross-section of a` comb so 'formed with a binding-strip on the head.

The blank for the comb-head (seen in Fig. l) compresses the head proper, a., which is folded along its middle to embrace the ends of the wire teeth b ZJ, and the prongs a* ax at its ends, which lfold together face to are soldered together, to form the guardteeth- In carrying out myinvention l prefer to, and generally do, proceed as follows:

l cutthe blank for the comb-head of the form shown in Fig. l from sheet metal and apply solder to one of its faces, or tin it. The solder is represented by the dotted line in Figs. la and l. l then fold this blank lengthwise along the line n fc in Fig. l, which gives the blank somewhat the appearance seen in Fig. lb. l now place the teeth between the plies of the folded head a, spacing them properly, and then submit the head to pressure which swages two tinned faces thereof meet and embed the teeth firmly in the metal of the head. The prongs ax LX are also brought together by the pressure until their finned faces meet and are pressed firmly together. Heat sufcient to melt the solder is now applied and the comb allowed to cool. It will then be found that the teeth b b are rigidly and permanently fixed in the head, and that the pairs of prongs a* will be joined two-and-two in a substantially integral manner, each two prongs forming a guard-tooth, h", having twice the thickness of the plate from which the prongs are formed.

ln pressing t-he head l may, and usually do, form a tubular stiffening-rib, a', along the upper edge of the comb. There the metal of the comb-head is quite thin relatively to the thickness of the teeth, l prefer to press the metal of the head in between the teeth, as represented in Figs. 2 and 4; but where the metal of the head has sufiicient thickness relatively to the teeth to warrant it l may, and usually do, simply press down the head with a flat-faced die, so that the teeth embed themselves wholly1 in the mass of the metal, as represented in Fig. en. In either case the faces of the plies of the folded head are brought tightly together between the teeth.

Figs. 5, 6, and 7 illustrate a slightly-different construction. ln this mode of manufacture l make the head of precisely the same form as that seen in Fig. l; but l form, also, a trough-like strip, d?, of sheet metal, provided face and l with periorations.(a3 in Fig. 7) in its bottom the metal of the plies .of the head in between the teeth until the ICO for the teeth. The teeth b are inserted in the perforations and the strip a2 is placed between the plies of the head. The whole is then submitted to pressure and heated to meltthe solder, as above described. A coating of solder may be applied to the outer faces of that portion of strip a2 that is embraced between the plies of the head in order to effect a perfect joining of the two.

The teeth should have heads, or be roughened at their attached ends, orhave a Staple like form. They may be of round wire, or be of square, angular, r attened forms. I prefer round wire.

I do not limit myself to tinning or applying solder to the head for the purpose of securing the teeth b therein. The prongs a* to form the guard-teeth must. however, be sol` dered rigidly together; but this maybe effected after the pressing, though not so conveniently nor so well.

It is not absolutely essential that the blank l for the head should be formed in 011e piece and bent to the form seen in Fig. l". The said blank may be in two like parts, as would be represented by cutting the blank seen in Fig. l along the line This is represented in Figs. 8, 8, and 8. The latter gure represents the two like parts or sections placed face to face.

9a, to cover the joint at the back of the head and add stiffness to the latter.

spect to the blank.

I may say that in carrying out myinvention I space, hold, and arrange the teeth b by clamping them between plates or dies, the attaching ends being exposed, so that the head may be placed thereon and swaged down; but this inode of holding the teeth is not new in the manufacture of combs.

Having thus 'described my invention, I claim*- l. The herein-described method of making toiletfcombs, which consists in irst forming the blank for the head of the comb of sheet metal with integral prongs ax ax, then applying a film of solder to the oneface. of each of said prongs, thenplacing the metal teeth of the comb between the' plies of the head and subjecting' the whole to pressure, as described, then heating the comb until the solder melts, and then cooling it, substantially as set forth.

2. A comb having its head and guard-teeth formed of two thicknesses or plies of sheet metal of like form, placed face to face and soldered together, substantially as set forth.

3. A comb having its head and guard-teeth formed of a sheet-metal blank comprising the body aand four prongs, ax af, said blank being folded `along the line and the prongs LX ctx thus broughtface to face-in pairs unitedv by solder to form the tially as set forth. i

In witness whereof I have hereunto signed my name in the witnesses.
